Thanks so much, everybody, for the great detailedadvice. I haven't had any problem with a cracked engine block, but am glad to be aware of it. I don't belong to Costco, but should probably consider joining if the prices are better. I spoke with my Honda dealership yesterday and the guy there told me that I should buy only the tires that are meant for the Honda Civic. I asked about Michelin, instead, and he said: "Nope, you should buy only the tires that come with the car." Now I'm stumped. Why is this necessary? If I bought Michelin, would my warranty be voided?

On another note: Riddle, how do you like the CR-V? My Civic has only 17,000 miles and no damage, and I have considered trading it in either for a Prius or a CR-V. On the other hand, my car will be paid off this November and I do like the idea of not having a car payment.
